Health Risks and Recommendations for Vaping After Quitting Smoking

Health Risks of Vaping

  • Nicotine, regardless of delivery method, is highly addictive and affects many body systems, mediators, and metabolic pathways 3
  • Nicotine has significant cardiovascular effects and may play a major role in the development of coronary artery disease, atherosclerosis, and aortic aneurysms 3
  • Vaping products contain and emit numerous potentially toxic substances beyond just nicotine 4
  • Vaping with e-cigarettes affects the cardiovascular and respiratory systems, contradicting perceptions that e-cigarette use is harmless 5

Comparison to Smoking Cessation

  • The US Preventive Services Task Force recommends focusing on proven behavioral counseling and FDA-approved pharmacotherapy for smoking cessation rather than e-cigarettes 4
  • E-cigarettes are not approved as smoking cessation aids by regulatory agencies, unlike standard nicotine replacement therapies 3

Public Health Concerns

  • The Forum of International Respiratory Societies recommends that electronic nicotine delivery devices should be restricted or banned until more information about their safety is available 2
  • Passive inhalation of vaporized droplets, particles, nicotine, and other substances into indoor air may have significant adverse health effects 3

Recommendations for Former Smokers

  • Individuals with a history of tobacco use should be advised to avoid vaping and using e-cigarettes, either as an approach to stop smoking or as a recreational activity 5
  • Evidence-based behavioral strategies and pharmacotherapy should be used to support complete nicotine cessation 5
